How Much Fabric Do I Need For A 20×20 Pillow?

To craft a 20×20 pillow, you will need a piece of fabric that is slightly larger than the actual dimensions of the pillow to account for seam allowances. A common recommendation is to add an additional 1 inch on each side for seam allowances. Therefore, for each side of the pillow, you should aim for a piece of fabric that measures 22×22 inches. Since a pillow has two sides, if you’re using the same fabric for both the front and the back, you will need a total of two pieces of 22×22 inches of fabric, which is approximately 1.25 yards.

Understanding Fabric Measurements for Pillows

Before you start cutting fabric for your 20×20 pillow, it’s vital to understand how fabric is typically sold and measured. Fabric is usually sold by the yard or meter, with a standard yard being 36 inches long. The width of the fabric, however, can vary greatly. Common widths are 36 inches (one yard), 44/45 inches, 54 inches, and 60 inches, although other widths are also available. When purchasing fabric, you must consider both the width of the fabric and the length you need to accommodate your project dimensions.

To make a 20×20 pillow, if your chosen fabric comes in a standard 45-inch width, purchasing 1.25 yards will give you enough fabric to cut out two squares with extra for seam allowances. Always round up to account for any shrinkage or cutting errors that might occur.

Calculating Fabric for the Pillow Front and Back

1. Decide on the seam allowance you will use. A 1-inch seam allowance is commonly recommended for pillows, as it provides enough fabric to work with and creates a durable seam. If you are a beginner, a larger seam allowance could make sewing easier.

2. Add the seam allowance to each side of the pillow dimensions. If using a 1-inch seam allowance, add 2 inches to each dimension of the pillow to allow for the seam on both sides. This makes the cutting dimensions for each piece of fabric – 20 inches (pillow size) + 2 inches (seam allowance) = 22 inches.

3. Multiply the adjusted dimension by 2 because you have to cut two pieces for one pillow.

4. Convert the measurement to yards by dividing by 36 (since there are 36 inches in a yard). For a 22×22 inch piece, you’ll need a little over 0.6 yards of fabric for each side of the pillow. So for both sides, you will need slightly more than 1.2 yards, which rounds up to 1.25 yards to allow for any errors or shrinkage.

Other Factors to Consider

Pattern Matching

If the fabric you’ve chosen has a pattern or print you wish to center or match up, you will need to purchase extra fabric. This ensures the pattern aligns at the seams or has the desired placement on the front of the pillow. To do this, you’ll need to determine the repeat of the pattern – the length it takes before the pattern repeats itself – and then accommodate this in the amount of fabric you buy.

Shrinkage

Remember that some fabrics can shrink after washing. Pre-wash your fabric before cutting and sewing if you plan on washing your finished pillow cover. This precaution will help you avoid a cover that ends up being too small after the first wash.

Fabric Type

The type of fabric you select for your pillow project can also affect how much fabric you’ll need. Some fabrics have more give or stretch than others. If you’re using a stretchy material, you may not need as much of a seam allowance, but using a non-stretchy, sturdy fabric will require accurate seam allowance for a snug fit of the pillow form.

Additional Pillow Components

Consider if you want to add any decorative elements like ruffles, piping, or borders to your pillow. These additions require extra fabric and should be factored into your total fabric calculations from the start.

Step-by-Step Fabric Calculation

Let’s break down these considerations into a step-by-step guide to help you calculate your fabric needs more precisely:

1. **Choose your fabric:** Decide on the material that fits your project’s aesthetic and functional needs.

2. **Account for pattern repeat (if necessary):** If working with a patterned fabric, determine the pattern’s repeat and factor this into your fabric quantity.

3. **Plan for shrinkage:** Pre-wash the fabric if necessary to prevent future shrinkage of the finished product.

4. **Decide on extra elements:** Determine whether you want to add decorative details such as frills, piping, or trims, and calculate the extra fabric these will require.

5. **Measure the fabric:** Use the calculated measurements to mark out the fabric pieces you’ll need to cut. Be sure to measure twice and cut once to avoid any mistakes.

6. **Cut the fabric:** Carefully cut your pieces, ensuring that they’re as accurate as possible to the dimensions you’ve calculated.

Remember, it’s always better to err on the side of having a little more fabric than you think you’ll need, rather than less. This way, you can account for any potential mistakes or design changes as you move forward with your project.

Finishing Thoughts

Crafting a homemade pillow cover can be a satisfying project that adds a personal touch to your home decor. By meticulously calculating and acquiring the necessary amount of fabric for your 20×20 pillow, you ensure the project runs smoothly from start to finish. Take into account the various factors that could affect fabric quantity such as pattern repeats, seam allowances, and potential shrinkage. Keep in mind, these considerations not only apply to a 20×20 pillow but can also be adjusted and applied to pillows of all sizes. With the right preparations, your custom pillow will look both professional and cozy upon completion.
